Application filed August 31, 1929. Serial 10.389353.

My invention belongs to that eneral class of devices known as windshielwipers or squeegees and relates more'particularly to an improved type ofwiper blade or swipe, as it is generally known.

The invention has among its objects the production of a simple, durable,eflicient, inexpensi ve and satisfactory device of the kind describedfor use wherever found applicable.

' be less inclined to smear and will not be rendered inoperative orineflicient through the accumulation of snow, ice, dirt or mud on, or initself, the same being substantially selfcleaning at all times.

Many other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from thedisclosure herein given.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like orcorresponding parts:

Fig. 1 is a side elevation of my improved applied to a windshield glass;

wiper ig. 2 is an enlarged sectional view taken substantially on theline 22 of Fig. 1;

Fig. 3 is the same view of the blade in operative relation with thesurface to be Wi ed; and

ig. 4 is a perspective view of a ortion of the rubber strip. p

Referring to the drawings in which a preferred embodiment of theinvention is shown, it may be mentioned that the blade is an improvementin the type illustrated in my pending application, Serial No. 337,041,and consists of a blade preferably of rubber consisting of a body partprovided with a head having a plurality of arrises extendin from end toend thereof. I have designate the blade generally by the numeral 1, thesame consisting of a body part 2, rovided with a rib or enlarged rib 3extending along the back or rear edge thereof. The opposite edge of thebody part 2 is enlarged as indicated at 4 and provided with the shoulderportions 5. At this edge there is provided the head 6, which isconnected to the body part or edge 4 by a hinge portion 7 of reducedsize, so that the same is comparativel flexible and constitutes a hingewhereby t e head portion may be flexed from one side to the other forexample as shown in Fig. 3. The head is comparatively thick so that initself it does not flex or yield to any extent, other than to closel huthe surface to be wiped and is provide wit arrises 8, substantiallysimilar to those shown in my pending application referred to.

The blade 1 is mounted in a holder 9 which consists of a channel orU-shaped member preferably formed with an enlarged loop at the closedside with the outer ends flared as indicated at 11, so as to closely fitthe body portion 2, and of a width or size so as to engage at theshoulders the edge portion 4 of the body. The blade is adapted to bemoved over a surface to be wi ed or squeegeed as for example the outerace of a windshield glass 12, it being immaterial whether the blade 'ismoved back and forth in a. straight line or moved in an are by means ofa spring arm carried by a rock shaft. For purposes of illustration, Ihave shown the last mentioned type of actuating means, which 16 reresents the arm that swings back and fort As shown the holder 9 isprovided with an through the rubber blade. A clamping member is securedby a bolt 17 and nut 18 and connects the holder with the arm 16. As

opening 14 which opening also extends As the device is moved back andforth over the surface to be wiped the blade is flexed back and forth atthe hinge portion 7, there being also some slight play between holderand the sides 19 of the clamp. The head 6 is at all times maintained incontact with the face to be wiped and maintains uniform engagementtherewith regardless of variations, in the surface or lack of carefulfitting of the clamps, etc., so the wiping tends always to be uniformand even. Obviously no dirt, snow, or thelike can get in between theholder and the wiping blade, and the blade is firmly held in place inthe holder. Should any water, dirt, snow or ice get in the space 7'adjacent the hinge, the head working back and forth during the flexingof the hinge portion causes the same to drop out and the device thuscleans itself. It will be noted that the shoulders formed at 55 form astop for the head and these also at all times prevent the metal edge ofthe holder coming in contact with the glass or surface wiped. The deviceis inexpensive to manufacture and is applicable on practically any typeof wiper or squeegee and has a comparatively long life in use.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departing fromthe spirit of my invention; hence, I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. A flexible wiping element for a squeegee, consisting of a body partprovided with a rib on one edge of greater thickness than the adjacentbody portion, and with a head on the opposite edge, said head and bodybeing integrally connected together by a hinge portion of a thicknessless than the thickness of the adjacent body and head, whereby the headmay be flexed back and forth at the hinge, the body portion constitutinga stop for the head remote from said hinge portion, thereby limiting themovement of the head when flexed to either side.

2. A flexible wiping element for a squeegee, consisting of a body partprovided with enlarged rib portion on one edge of a greater thicknessthan the adjacent body portion, and with a head on the opposite edge,said head and body being integrally connected together by a hingeportion of a thickness less than the thickness of the adjacent body andhead, whereby the head may be flexed back and forth at the hinge, thebody portion constituting a stop for the head remote from said hingeportion, thereby limiting the movement of the head when flexed to eitherside, the head tapering outwardly from the edge at the juncture with thehinge, and provided with a plurality of wiping edges.

Patent dated April 12, 193

As the device is moved back and forth over the surface to be wiped theblade is flexed back and forth at the hinge portion 7, there being alsosome slight play between holder and the sides 19 of the clamp. The head6 is at all times maintained in contact with the face to be wiped andmaintains uniform engagement therewith regardless of variations, in thesurface or lack of careful fitting of the clamps, etc., so the wipingtends always to be uniform and even. Obviously no dirt, snow, or thelikecan get in between the holder and the wiping blade, and the blade isfirmly held in place in the holder. Should any water, dirt, snow or iceget in the space 7' adjacent the hinge, the head working back and forthduring the flexing of the hinge portion causes the same to drop out andthe device thus cleans itself. It will be noted that the shouldersformed at 55 form a stop for the head and these also at all timesprevent the metal edge of the holder coming in contact with the glass orsurface wiped. The device is inexpensive to manufacture and isapplicable on practically any type of wiper or squeegee and has acomparatively long life in use.
